Along with the advances in polymer solar cells (PSCs), the accurate evaluation of novel photovoltaic polymers with various band gaps is an important issue that should be concerned, as well as needs to be addressed at various research laboratories in the world. In this work, we have focused on PSCs by employing some of the most efficient and well-known low band gap (LBG) polymers, for instance, PBDTTT-C-T, PBDTBDD, PDPP3T, PTB7-Th, PSBTBT and PBDTTPD, and obtained the corresponding spectral-mismatch factors (MMFs) under various reference cell/solar simulator combinations. Generally, there still exists ±25% spectral error even for a simulator whose spectrum grade is labeled as AAA. The best way to accurately evaluate the power conversion efficiencies (PCEs) of LBG polymers is by choosing a combination of a spectral-matched-silicon-solar-cell (match to LBG polymer's spectral responsivity spectrum) and a Class AAA solar simulator. Furthermore, our results could provide guidance for the accurate measurements of organic molecules, perovskites, and related photovoltaic technologies.

该工作在基于不同（4种等级的）太阳光模拟器/（6种响应范围的）标准硅电池组合的条件下分别测算了9种具有不同带隙（光谱响应）的光伏材料的光谱适配因子，据此他们提出了新型太阳能电池的效率准确测量的通用方法，可用于有机小分子、聚合物、钙钛矿等多类太阳能电池研究中。该工作发表在英国皇家化学会旗下的Journal of Materials Chemistry C上，引起国内外同行的广泛兴趣，并入选该期刊Most Read Articles第二名。
